John Allen Astin (born March 30, 1930) is an American actor who has appeared in numerous films and television shows, as well as a television director and voice artist and is known for the role of Gomez Addams on The Addams Family, and having been married to actress Patty Duke.

Astin started in theater, making his first Broadway appearance as an understudy in Major Barbara, and also did voice-over work for commercials. His first big break in film came with a small part in West Side Story in 1961.

Astin received an Academy Award nomination for Prelude, a short film that he wrote, produced, and directed. He was nominated for an Ace Award for his work on Tales from the Crypt, and received an Emmy nomination for the cartoon voice of Gomez on ABC-TV's The Addams Family. He also voiced the character Bull Gator on the animated series Taz-Mania. Astin served for four years on the Board of Directors of the Writers Guild of America, and has been active in community affairs in Los Angeles and Santa Monica.

We all struggle, and I had plenty of that, but I've had a great time. I've done hundreds of TV shows and 30 to 40 movies, and I love acting. I'm very happy having done the Poe. That's been really terrific.

Astin currently teaches both acting and directing in the Theater Arts and Studies Department at Johns Hopkins University, his alma mater. Commenting on his dual career, he said in 2007, "I don't know one major university that has a known actor teaching every day." He hopes to re-establish a drama major at the university, noting that he is one of only a handful to earn a drama degree from Hopkins. Astin can be seen singing and playing cowbell in a music video from JHU released in December 2009.[citation needed]

Astin has five sons; three (David, Allen, and Tom) with his first wife, Suzanne Hahn; two with his second wife, actress Patty Duke – one adopted (Sean, Patty's son from an earlier relationship, whom John adopted after their marriage) and one biological (Mackenzie). Astin is currently married to Valerie Ann Sandobal and lives in Baltimore. He practices Nichiren Buddhism as a member of the worldwide Buddhist association Soka Gakkai International.[5]
